Liling Xing Tai Long Special Ceramic Co., LtdSintyron In the upgrading of global high-end manufacturing, precision fluid control systems are widely applied in new energy, semiconductor, chemical engineering, medical equipment and environmental protection industries. As a core wearable and corrosion-resistant component of metering pumps, booster pumps and fluid delivery equipment,
high-purity alumina ceramic plungers
have gradually replaced traditional metal plungers, becoming a key part to improve equipment stability, reduce maintenance costs and upgrade industrial manufacturing standards.
Different from stainless steel and alloy plungers, our alumina ceramic plungers are made of 95%–99.7% high-purity alumina raw materials, formed by high-temperature sintering and ultra-precision grinding technology. With Mohs hardness up to grade 9, second only to diamond, the product boasts excellent comprehensive physical and chemical properties, completely solving the pain points of short service life, easy corrosion and low precision of traditional metal plungers in harsh working conditions.
Core Performance Advantages: Empower High-Stability Industrial Operation
First, ultra-high wear resistance and long service life. The wear resistance of alumina ceramic plungers is 10–20 times that of ordinary stainless steel. In high-frequency reciprocating motion and medium containing fine particles, the service life can be extended 3–8 times compared with metal products. In lithium battery slurry delivery and coating equipment scenarios, the continuous working life reaches 5000 hours, which greatly reduces the frequency of parts replacement and equipment downtime loss for enterprises.
Second, strong chemical corrosion resistance and high purity stability. The alumina ceramic material features inert chemical properties, which can stably adapt to harsh media such as strong acid, strong alkali, salt water and organic solvents. It will not produce oxidation, corrosion or metal ion precipitation during operation. It effectively avoids medium pollution, fully meets the high-purity fluid control requirements of semiconductor microelectronics, pharmaceutical delivery and pure water preparation industries, and guarantees product yield and production safety.
Third, micron-level precision and low friction performance. After ultra-precision polishing, the plunger surface is smooth without burrs, with the machining accuracy controlled within ±0.001mm. The precise fit gap ensures ultra-low flow pulsation and stable metering accuracy in long-term operation. Meanwhile, the low friction coefficient reduces equipment operating resistance and energy consumption, realizing energy-saving and efficient operation of fluid equipment.
In addition, the product has excellent high-temperature resistance and electrical insulation performance, which can work stably in a high-temperature environment of 1600℃, and is suitable for high-voltage and special working condition scenarios, with strong environmental adaptability.
Wide Application Scenarios: Cover High-End Industrial Core Fields
